I will be sleeping at the Radison National airport two nights and walking to a meeting at the Doubletree a little north later this month. Which are the two best value-for-the-money restaurants that are either within walking distance (~2 mi.) or are worth the cab ride. Price and ethnicity unimportant. I just want to lean back in my chair at the end of the meal and think "Those D.C. Hounds know that of which they speak."
